AIM High-grade Ewing sarcomas and Primitive neuroectodermal tumours (PNET) make up the tumours of the Ewing family. Our purpose was to evaluate the value of [18F]fluorodeoxyglucose positron emission tomography (FDG PET) in patients with Ewing tumours. PATIENTS AND METHODS Twenty-four patients who had PET because of a suspected Ewing tumour during a 5-year(More)
The aim of this study was to define the imaging characteristics of primary and recurrent gastrointestinal stromal tumors (GIST) in computed tomography with respect to the tumor size. Computed tomography was performed in 35 patients with histologically confirmed gastrointestinal stromal tumors and analyzed retrospectively by two experienced and independent(More)
OBJECTIVES To investigate the effects, digital impression procedures can have on the three-dimensional fit of ceramic partial crowns in vitro. METHODS An acrylic model of a mandibular first molar was prepared to receive a partial coverage all-ceramic crown (mesio-occlusal-distal inlay preparation with reduction of all cusps and rounded shoulder finish(More)
PURPOSE To assess pulmonary abnormalities in patients with primary Sjogren's syndrome (PSS) using high-resolution computed tomography (HRCT). MATERIAL AND METHODS The HRCT scans of 24 patients with the diagnosis PSS were retrospectively reviewed regarding the presence, extension and distribution of 16 pathological findings. RESULTS Nineteen patients(More)
To adequately perform perioral rejuvenation procedures, it is necessary to understand the morphologic changes caused by facial aging. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate such changes. Photographs of 346 male individuals were evaluated using 12 anthropometric indices. Data from two groups of(More)
The initial localization of metastases in the bone in patients with solid tumors has a relatively good prognosis in comparison with visceral metastasization. The early detection of bone marrow metastases allows for a rapid initiation of therapy and a subsequent reduction in the morbidity rate. Modern MRI is superior to the 30-year-old skeletal scintigraphy(More)
Between 1998 to 2000, the shoulders of 17 patients with rotator cuff tears were examined using magnetic resonance imaging preoperatively, and 6 and 12 months after open surgical repair. To assess the course of the supraspinatus muscle atrophy, the easily reproducible magnetic resonance imaging parameters occupation ratio and tangent sign in the Y-shaped(More)
The parallel measurement of specific and nonspecific CyA levels by second generation radioimmunoassays based on monoclonal antibodies proved to be an effective procedure to monitor both parent CyA levels and the capacity to eliminate its metabolite. Using this monitoring procedure it could be shown that CyA-associated nephrotoxicity in the early course(More)
Skeletal metastases commonly occur in patients with cancer and treatment is necessary to alleviate pain and prevent complications, such as mobility deficiencies and pathologic fractures. The authors present a patient with a stage IV malignant melanoma and a pathologic fracture of the left tibial plateau treated with radiofrequency heat ablation and(More)
